My new 2021 SL (Super Light) ebike is very light and agile, so it feels and handles a lot like a regular mountain bike - except of course for the super smooth, quiet but powerful electric motor. Since I ride both on single tracks and forest roads in the steep Appalachian mountains, and I also ride on byways and rural roads, I swapped the standard All Mountain tires for Fast Trak 50/50 On/Off road tires. These have a narrow center tread that is fast and quiet on the highway but lean the bike into a turn on or off road and the knobby tread really digs in for excellent carving. Then I exchanged the chainring from 30T to 34T for faster and easier highway travel, yet it still has enough low gears and e-power to climb amazingly steep hills. So now this bike is an all-purpose adventure e-bike - I can go anywhere. Using the Mission Control app, I have carefully tuned the electric motor 3-level response. In Eco: 25 Sustain, 80 Peak, Sport: 50 Sus, 90 Pk, Turbo: 70 Sus, 100 Pk. These setting are great for on or off road. On road I can usually stay in Eco and get 60+ miles in moderately hilly terrain with only a few thousand feet ascent. With steeper hills I switch into Sport sometimes and still get 45 miles per charge. With the new tires, this bike can fly downhill, easily hitting 40-45MPH just coasting. The excellent (carefully tuned) air suspension makes this bicycle handle and corner like a very fine motorcycle. The SRAM hydraulic brakes are perfect, not too grabby for great control in downhill dirt or gravel but powerful enough to bring my 185 lbs to stop with just light pulls on the levers. I did saw off 7/8"" from each end of the too-wide handlebar. The big 29 x 2.3 tires offer amazing stability on/off road, so even when standing up and pedaling hard, the bike stays on a straight line course. I am 72, and this bike allows me to ride anywhere I want to go - it makes me feel like I'm half my age!. A great eBike for outdoor adventuring.
